Birthday Cake Built from Pantry Scraps: Matcha, Yuzu & Brown Butter for One

Inga Lam challenges herself to bake a solo birthday cake using only ingredients already in her kitchen — no grocery run allowed. She improvises a honey matcha sponge with emergency buttermilk, brown butter, and lemon zest, then tops it with yuzu Swiss meringue buttercream and two-toned whipped cream. A charming, low-key celebration bake that's equal parts personal experiment and genuine recipe inspiration.
